The United Nations Environment Program estimates that 150 to 200 species go extinct every day, which is about 10 to 100 times the "background," or natural, rate of extinction.

One problem facing endangered species, particularly in developing countries, is poaching. Driven in part by the demand for animal parts in traditional medicine cures in parts of Asia, poaching (and capture of animals for the pet trade) has only increased — dramatically — in the past decade.

But humans are animals who come from a world replete with other creatures and forms of life. Even now, surrounded as many of you are by urban centers, devoid of forests and most wildlife, people depend on plants and animals for survival. Ultimately the loss of biodiversity will hurt you, as you, dear humans, are part of the web of life. Each species serves a specific function that can't be wholly replaced if one goes extinct, leading to a less productive ecosystem which ultimately provides fewer benefits for humans.

Wolves play a very important role in the ecosystems in which they live. Since 1995, when wolves were reintroduced to the American West, research has shown that in many places they have helped revitalize and restore ecosystems.

They improve habitat and increase populations of countless species from birds of prey to pronghorn, and even trout. The presence of wolves influences the population and behavior of their prey, changing the browsing and foraging patterns of prey animals and how they move about the land.

This, in turn, ripples throughout plant and animal communities, often altering the landscape itself. For this reason wolves are described as a “keystone species,” whose presence is vital to maintaining the health, structure and balance of ecosystems.
